parser xml, problém diakritika

ahoj,

poraďte prosím s jednou chybkou u xml parseru, při předávání text řetězce do pole se textový řetězec rozdělí pokud narazí na dikaritiku. Nemohu přijít na to proč.

V tomto řádku
//category
if ($this->priv_znacka == "NAME" and $jecategory) {$this->cur_category['name'] = $data;}

pokud $data obsahuje např.: "Baterie do digitálních fotoaprátů" rozdělí to na "Baterie do digit" a "álních fotoaparátů", vyzkoušeno i bez mb_convert_encoding

nemohu přijít na to kde je problém

moc díky za pomoc
petr
